numbers of moles of CO2
« on: October 24, 2011, 06:12:37 PM »
Hi
I have a 3.95cm3 of CO2 in the 5cm3 sample
The preasure of CO2 is:
Pco2=Patm-Ph2o=760-92.51=667.49
How to calculate the numbers of moles of CO2 in the 5cm3 of sample?

If you are given a volume of CO2 I would assume it means care was taken of the water partial pressure, as if not, volume of CO2 is lower than 3.95cm3 - so reporting it as 3.95cm3 in 5cm3 makes no sense and is ambiguous.
